Be it known that I, ERNEST FREDERICK Goonrmn, a subject .ofjthe Kingdom of Great Britain, of Churchfield Mills, Dudley,

: in the county of WVorcester, England, have invented certain new and useful Im rovements in Machines for Finishing etallic Wheel-Rims, of whichthe following is a v specification.

'This invention relates toimprovements in machines for shaping the side flanges of metallic wheel rims, and particularly the rims of wheels of the type composed of two sheavesor halves, and a separate rim por-' tion, the edges of which are outwardly folded over the edges of the sheaves or halves. These three elements are combined together in such a manner that the rim por tion assumes a cross-section of shallow U- configuration, and afterward the sides of this rimiportion are bent or curled inwardly i by the application of driven rollers, one of which is located inwardly and the other outwardly of the side part of the said rim portion. The inner driven roller, is of con vex form and the outer driven roller is of concave form, so that a sidepart of the rim is thereby effectively molded or shaped between the appropriately shaped or formed peripheries of the rollers.

This invention is a division of my copending application forLetters Patent of the United States, Serial No. 306,417,'fi1ed.

June 24, 1919, allowed January 5, 1920.

In order that this invention may be clearly understood and readily carried into practice, reference may be had to the appended explanatory sheet of'drawings, upon which Figure 1 is a plan 'ing the side flanges of metallic .wheel rims inthis application. 7

'tured up to the-form shown in*Fi'g.-.2 is transferred to. the machine illustrated n plan in 1. This machine comprises means forv rotatably! mounting thewhe'el' about a horizontal axis in the. machine, for

which purpose the machine is provided with plate-like members 10 between which the wheelis adapted tobe gripped. The edges of said members are beveled on their opposing sides to fit the shoulders of the under sides of the flanges of the rim portion of the wheel as indicated by dotted lines, the 7 wheel rim being indicated at A. w is a hand-wheel for relatively adjusting the said plates w axially in order to receive the wheel. Rotation is adapted to be imparted to the said plates w and thereby to the wheel from suitablegearing z. 2 is a roller which may not be positively driven, but which is carried in a bracket by which it is adapted to be advancedtoward the rim in a direc tion in the plane of the wheel. This ad vancing of the roller 2 may be effected by any suitable mechanism operated, for instance, from the star wheel 3. 4; indicates a hand wheel for adjusting the roller 2 axially in relation tothe wheel being operated upon. The roller .Zis adapted to inwardly curl or bend both edges of the rim simultaneously, and for this purpose it is furnished with surfaces 5, 5 vof the form which the exterior of'the rim is required to assume, when finished. Shoulders 6, 6, in v the roller 2 are provided to form abutments limiting the extent to which, the edgesof the rim may be bent or rolled inwardly. As a result of the operation effected by this machine the rim is caused to assume the form shown in Fig.4. If a sufficient width or margin ,1) of metal ofthe annular member is folded over the edges of the sheaves, this margin of metal is in the rolling process intimately pressed into contact with the sheaves and a substautially water-tight joint is obtained. Cement may be-includedbetween the rim part and the sheaves before the folding process,

and thismay serve to render the joint sufficiently water-proof to render unnecessary any welding, brazing, or equivalent process.

e What I claim as my invention and desire to secure by'Letters Patent is 1. In a machine of the-class described,the combination of a pair of work gripping members mounted forrotation and provided with means for moving them to gripping or; releasing position, sald members being 012' culareand having their opposing sides' beve eled at the periphery to fitftherim flanges of finished workgend a roller also mounted for rotation andnrranged opposite the space between-said Work grippingmembers and provided with shoulders to limit the extent "to whieh the edges of the hook formations,

oft-he Work may be displaced inwardly.

2. In a maohinegofthe class described, the

releasing position, said members being circular and havlng their. opposlng sldes beveled at the periphery to fit the rim flanges of finished WOI'k; and a roller also mounted for rotation and arranged opposite the space-between said Work gripping members and provided with shoulders to limit the extent to which the edges of the hook formationsof the. Work may be displaced inwardly, and

beans to adjust said roller. 7

In Witness whereof have hereunto set- 'my hand. r
